AURIPHONE.

Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed October 6, 1914. Serial No. 865,333.

To all whom it may concern:

Be it known that 1, Amino LEYER, a citizen of the United States,residing at Dutch Flat, in the county of Placer and State of California,have invented certain new and useful Improvements in Auriphones, ofwhich the following is a specification.

This invention pertains to improvements in auriphones and analogous aidsfor hearing, having for its primary object to amplify sound, withoutmaterially minimizing its clarity.

A further object is to eliminate the use of artificial tympanums orother fragile instrumentalities, and to provide a durable structure ofan incuinbersome nature, which is highly efiicient for conveying soundto the inner ear.

Other objects as well as the nature, characteristic features, and scopeof my invention will be more readily understood from the followingdescription taken in connection with the accompanying drawings andpointed out in the claims forming a part of this specification.

Referring to the drawings: Figure 1 is a perspective view of a deviceconstructed in accordance with my invention, a portion of the tubethereof being broken away, Fig. 2 is a sectional view of the sameillustrating to advantage the reverberant spheroids through which thesound passes, and Fig. 3 is a horizontal sectional view illustrating toadvantage the interior of the housing and the spheroids used in thisinvention.

In the drawings wherein is illustrated the preferred embodiment of thisinvention, a housing 5 is provided, which in the present instance is ofa substantially hemispherical configuration and has detachably mountedtherein a perforated cap 6, which has an annular flange dependingtherefrom the latter snugly engaging the inner periphery of the housing5, as shown to advantage in Fig. 2. A foraminated disk 7 is arranged inthe housing having the central portion thereof cut out and engaged withthe outer periphery of a resonant crown 8, the latter being likewise ofa hemispherical configuration and has the marginal edge thereof eX-tended slightly below the foraminated disk 7, as likewise shown toadvantage in Fig. 2.

Mounted between the inner periphery of the housing 5 and the innerperiphery of the resonant crown 8 and in spaced relation thereto, are aplurality of reverberant spheroids, 9, said spheroids varying inconfiguration and being placed one within the other in spaced relationand provided with openings 10 through which the sound passes, asindicated by the arrow. It is seen that the openings 10 are non-alinedso as to require the sound to pass entirely through each one of the waysprovided by the plurality of spheroids, before passing therefrom intothe next way. The innermost of said spheroids is provided with a pair ofdiametrically opposite openings through which extends one end of a tube11, the terminal thereof being closed, while the opposite end in thedrawings is broken away, but it is to be understood that the tube is tobe placed in engagement with suitable ear engaging members which projectinto the auditory canals, acoustical impulses which enter through theperforated cap 6 are thereby communicated to the inner ear, since theend of the tube which is housed within the innermost of the spheroids 9,is provided with a plurality of openings 12, thereby permitting thesound to be emitted through said tube after having passed through all ofthe spheroids. In operation therefore, it is seen that the sound willfirst pass through the perforated cap 6 after which it takes the courseas indicated by the arrows in Fig. 2, through the foraminated disk 7 andsubsequently beneath the resonant crown S and into the spheroids 9 tothe tube 11.

It is, of course, understood that the device is of a relatively smallnature, so as to be placed on the person, and carried withoutinconvenience to the wearer.

It will be understood that the above description and accompanyingdrawings comprehend only the general and preferred embodiment of myinvention and that various minor changes in details of construction,proportion and arrangement of parts may be made within the scope of theappended claims and without sacrificing any of the advantages of myinvention.

Having thus fully described my invention, what- I claim as new anddesire to secure by Letters Patent is:

1. An auriphone including a housing having a perforated closure, aplurality of reverberant spheroids concentrically mounted in the housingand arranged one within the other, said spheroids being provided withnon-alining openings through which the sound passes whereby an evolutionof the sound in each spheroid is necessitated to increase its intensity,and a conducting tube extending from one of said spheroids and adaptedto engage the auditory canal for conveying sound thereinto.

2. An auriphone including a housing, a perforate cap detachablyassociated with said housing through which the sound passes to theinterior of the latter, a resonant crown mounted in said housing withwhich the sound contacts subsequent to passingthrough said perforatecap, a plurality or reverberant spnerolds mounted in the housing, saidspheroids being of variant sizes and adapted to be placed one within theother, each being provided with openings through which the sound passes,and a conducting tube engaged through the innermost of said spheroidsfor conveying sound from the housing after having passed through thespheroids.

3. An auriphone including housing, a perforate cap. detachahly mountedon said housing, a foraminated disk carried in said housing, a resonantcrown mounted on the disk, a plurality of reverberant spheroids arrangedone within the other and provided with openings through which the soundpasses, said openings being non-alined permitting a complete circulationof sound in each of said spheroids prior to passing therefrom, and atube engaged through said housing and with the innermost of saidspheroids for conveying sound therefrom.

In testimony whereof I my signature in presence of two witnesses.

AMAND LEYER. Witnesses LOUIS FALLER, Mrs. Louis FALLER.
